Modeling dynamic location update strategies for PCS networks

Location management, accomplished through the backbone network and wireless links, is an important issue in a personal communication system (PCS). In this paper, we present a unified model to assess three dynamic location update strategies, including the distance-based, movement-based and time-based schemes, based on a seven-state Markovian mobility model on a two-dimensional hexagonal cellular topology. In our analysis, performance measures of each strategy can be evaluated efficiently.
